Description

Technical Field

[0001] This utility model relates to a signal receiving device, specifically a signal receiving device for a liquid crystal display terminal. Background Technology

[0002] When a monitor receives signals, if it is subjected to magnetic field interference, it may exhibit phenomena such as no display, image errors, garbled characters or dots, image shifting, or inversion. These interferences may affect the normal operation and display quality of the monitor. Magnetic field interference may originate from electromagnetic interference on power lines or signal lines, or from erroneous waveforms on control signal lines. These interference signals may incorrectly modify register parameters or write data to the display unit, leading to display abnormalities.

[0003] Current signal receiving devices for LCD display terminals generally include a housing and a main body of the signal receiver located inside the housing. However, the housing usually does not have an anti-magnetic structure, which makes the operation of the signal receiver susceptible to magnetic fields. Utility Model Content

[0004] The purpose of this invention is to provide a signal receiving device for a liquid crystal display terminal to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides a signal receiving device for a liquid crystal display terminal, including a housing and a signal receiver body disposed inside the housing. The housing is divided into an upper housing and a lower housing. The inner walls of the upper housing and the lower housing are provided with slots. An insulating layer is inserted into the inside of the slots. A shielding layer is fixedly disposed around the outer walls of the housing.

[0006] Furthermore, multiple uprights are fixedly installed on the inner wall of the lower box, and each upright has a pin hole inside. Multiple pins are correspondingly installed on the bottom of the upper box. The pins are inserted into the pin holes. By inserting the pins into the pin holes, the upper and lower boxes are spliced ​​together. This splicing not only simplifies the manufacturing and installation process, making the operation more convenient, but also has a relatively low cost. Moreover, there is no overly complicated structure when assembling and separating, so disassembly is very convenient and the connection effect is good.

[0007] Furthermore, a through hole is provided on one side of the lower housing, and a wire is installed inside the through hole to connect the signal receiver body of the housing to the outside.

[0008] Furthermore, the top of the upper box is provided with glass plates, bolt holes, and grooves.

[0009] Furthermore, the bolt hole is located at one end of the upper box body, and the groove is located on both sides of the upper box body, with the bolt hole and the groove arranged symmetrically.

[0010] Furthermore, the bolt holes are internally threaded with bolts, which further enhances the stability of the connection between the upper and lower boxes.

[0011] 1. In this utility model, by setting a shielding layer, when a magnetic field passes through the shielding layer, a large amount of the magnetic field cannot pass through the shielding layer and affect the main body of the signal receiver inside the box. However, a very small number of high-intensity magnetic fields will pass through the box. When the magnetic field comes into contact with the surface of the isolation layer, it will be reduced to the weakest level under the action of the isolation layer. In this way, it will not affect the normal operation of the main body of the signal receiver inside the box.

[0012] 2. In this utility model, multiple columns are set around the inner wall of the lower box, and pin holes are opened inside the columns. Multiple pins are set at the bottom of the upper box, and the pins are inserted into the pin holes to splice the upper and lower boxes together. This not only simplifies the manufacturing and installation process and makes the operation more convenient, but also has a relatively low cost. Moreover, there is no overly complicated structure when assembling and separating, so disassembly is very convenient and the connection effect is good. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3This utility model provides a technical solution: a signal receiving device for a liquid crystal display terminal, including a housing 1 and a signal receiver body disposed inside the housing 1. The housing 1 is divided into an upper housing and a lower housing. The signal receiver body can be installed in the lower housing using fasteners such as screws, or it can be connected by snap-fit ​​or other snap-fit ​​methods, without limitation. The inner walls of both housing parts 1 are provided with slots 2. The slots 2 are arranged along the perimeter of the housing 1 in a "U" shape. An insulating layer 3 is inserted into the inside of the slot 2. A shielding layer 4 is fixedly disposed around the outer walls of the housing 1. A through hole 8 is provided on one side of the lower housing part 1.

[0019] In practice, the main body of the signal receiver inside the box 1 is first connected to the external circuit through a wire. When the power is turned on, the main body of the signal receiver inside the box 1 starts to work. When the main body of the signal receiver inside the box 1 is working, it may be affected by magnetic fields, resulting in signal interference and other issues that affect its operation.

[0020] A shielding layer 4 is provided around the outer wall of the housing 1. When a magnetic field passes through the shielding layer 4, a large amount of the magnetic field cannot pass through the shielding layer 4 and thus cannot affect the signal receiver inside the housing 1. However, a very small number of strong magnetic fields can pass through the housing 1 and encounter the insulating layer 3. When the magnetic field comes into contact with the surface of the insulating layer 3, the resistance of the insulating layer 3 and the shielding layer 4 changes under the influence of the magnetic field. When the magnetoresistive material is subjected to an external magnetic field, the transport properties of the electrons inside it will change, resulting in a change in the resistance value. This change can be indirectly reflected by measuring the resistance, thereby achieving the effect of magnetic blocking and reducing the magnetic field to its weakest point. In this way, it will not affect the normal operation of the signal receiver inside the housing 1, which helps to avoid interference from the magnetic field to the signal receiver.

[0021] See Figure 1-3 As shown, multiple columns 5 are fixedly installed on the inner wall of the lower box 1. Each column 5 has a pin hole 6 inside. Multiple pins 7 are correspondingly installed at the bottom of the upper box. The pins 7 are inserted into the pin holes 6. The top of the upper box is provided with a glass plate 9, bolt holes 10 and grooves 11. The bolt holes 10 are located at one end of the upper box, and the grooves 11 are located on both sides of the upper box 1. The bolt holes 10 and the grooves 11 are symmetrically arranged. Bolts are threaded into the bolt holes 10.

[0022] In practice, multiple pillars 5 are set around the inner wall of the lower box, and pin holes 6 are opened inside the pillars 5. Multiple pins 7 are set at the bottom of the upper box 1. The pins 7 are inserted into the pin holes 6, and the upper and lower boxes are spliced ​​together. This splicing not only simplifies the manufacturing and installation process, making the operation more convenient, but also has a relatively low cost. Moreover, there is no overly complicated structure when assembling and separating, so disassembly is very convenient and the connection effect is good.

[0023] Furthermore, the principle of the insulating layer 3 and the shielding layer 4 is mainly based on the magnetoresistive effect, which is the phenomenon that the resistance of a material changes under the influence of a magnetic field. When a magnetoresistive material is subjected to an external magnetic field, the transport properties of its internal electrons change, leading to a change in resistance. This change can be indirectly reflected by measuring the resistance, thereby achieving the effect of magnetic resistance. The insulating layer 3 and the shielding layer 4 have advantages such as high sensitivity, fast response, low energy consumption, and low cost, and are widely used in various fields of magnetic field measurement, sensors, and transducers. In this invention, the preferred material for the insulating layer 3 and the shielding layer 4 is graphene.

[0024] Working principle: First, the main body of the signal receiver inside the box 1 is connected to the external circuit through wires. When the power is turned on, the main body of the signal receiver inside the box 1 starts to work. When the main body of the signal receiver inside the box 1 is working, since the working environment is outside, the external environment is varied and may be affected by magnetic fields.

[0025] A shielding layer 4 is provided around the outer wall of the box 1. When a magnetic field passes through the shielding layer 4, a large amount of the magnetic field cannot pass through the shielding layer 4 and will not affect the main body of the signal receiver inside the box 1. However, a very small number of magnetic fields with high intensity will pass through the box 1. At this time, they will encounter the isolation layer 3. When the magnetic field comes into contact with the surface of the isolation layer 3, the resistance of the isolation layer 3 and the shielding layer 4 will change under the action of the magnetic field.

[0026] When a magnetoresistive material is subjected to an external magnetic field, the transport properties of its internal electrons change, leading to a change in its resistance. This change can be indirectly reflected by measuring the resistance, thus achieving a magnetoresistive effect and reducing the magnetic field to its weakest point. This prevents the normal operation of the signal receiver inside the housing 1 from being affected, and helps to avoid interference from the magnetic field to the signal receiver.

[0027] By setting multiple pillars 5 around the inner wall of the lower box, and opening pin holes 6 inside the pillars 5, and setting multiple pins 7 at the bottom of the upper box 1, the upper and lower box 1 are spliced ​​together by inserting the pins 7 into the pin holes 6. This splicing not only simplifies the manufacturing and installation process, making the operation more convenient, but also has a relatively low cost. Moreover, there is no overly complicated structure when assembling and separating, so disassembly is very convenient and the connection effect is good.
